* refactor(privacy_preserving_circuit): extract functions for readability
* refactor(privacy_preserving_circuit): address PR review comments
Bundle shared handle_* arguments into PrivateOutputHandler struct in
output.rs and fix misplaced docstring on resolve_external_seed in
execution_state.rs.
* feat: update commitment mechanism for new private account (#546)
* refactor(privacy_preserving_circuit): extract functions for readability
* feat: update commitment mechanism for new private accounts
Allow init accounts to optionally use a real membership proof for
DUMMY_COMMITMENT instead of hardcoding DUMMY_COMMITMENT_HASH as the
CommitmentSetDigest. The wallet fetches the proof from the sequencer
and passes it through the circuit.
* fix: address clippy lints and fix integration test visibility
* add tests
* refactor: removed duplicated code
* refactor: simplify init nullifier mechanism
Replace Option<MembershipProof> with Option<CommitmentSetDigest> on init
variants (PrivateAuthorizedInit, PrivateUnauthorized, PrivatePdaInit).
The circuit now receives the commitment tree root directly instead of
recomputing it from a Merkle proof.
* refactor: use CommitmentSetDigest directly instead of Option for init commitment root
Address PR #546 review feedback: the circuit now accepts CommitmentSetDigest
directly on init variants (PrivateAuthorizedInit, PrivateUnauthorized,
PrivatePdaInit), with callers providing DUMMY_COMMITMENT_HASH as the default.
Also fixes duplicate resolve_external_seed from rebase and rebuilds artifacts.
* style: run cargo +nightly fmt
Rename os_random field to random_seed per review feedback. Fix tests
that constructed SharedSecretKey with a hardcoded EphemeralSecretKey
instead of deriving it via EphemeralSecretKey::new.
Introduce EphemeralSecretKey as a proper struct with EphemeralSecretKey::new()
that derives esk from SHA256("/LEE/v0.3/esk/" || account_id || os_random || nonce).
Rename witness field from esk to os_random. Simplify encapsulate_deterministic
to accept pre-derived EphemeralSecretKey directly.
